(a) length, mass, velocity

(b) length, time, velocity

(d) length, time, mass

(d.) Length, time, mass ✔

S.I unit of length is metre (m).

S.I unit of time is second (s).

S.I unit of mass is kilogram (kg).

________________________________

Quantities which are independent of other physical quantities or cannot be obtained by the combination of two or more quantities.

The units which can neither be derived from one another nor resolved broken into anything more basic are called fundamental units.

For example :-

Mass - kilogram

length - metre

Time - second

Temperature - kelvin

Quantities that can be obtained by the combination of two or more fundamental quantities are called drived quantities.

Any unit which can be obtained by the combination of one or more fundamental units is called derived unit.

For example:-

Acceleration - metre per square second

Velocity - metre per second

Momentum - kilogram metre per second

Force - kilogram metre per square second.
